I've exhausted all possible solutions in attempting to retrieve the value of an element by its id, but unfortunately nothing seems to be working. I am currently utilizing ASP.NET and have identified that the server modifies the id of TextBox1, hence we should use the clientID. Despite this knowledge, when I attempt to log data1, I receive a blank space or no output at all.
var data1 = document.getElementById('MainContent_TextBox1').textContent;
var data1 = document.getElementById("<%=MainContent_TextBox1.ClientID %>").value;
Below is the ASPX code snippet:
<asp:TextBox ID="TextBox1" runat="server" ></asp:TextBox>
And here is the corresponding JS code:
var data1 = document.getElementById('MainContent_TextBox1').textContent;
Upon checking the console, an error message is displayed:
Uncaught SyntaxError: Unexpected end of input and its reference in the master file!
The command console.log(data1); results in an empty output within the console.
If anyone has alternative suggestions or insights into why this code isn't functioning properly, please do share. Thank you!
